What s the best tier 4 car in nfs shift on ps3 once fully upgraded?

iwas wondering what the best car in nfs shift wa on my ps3 once fully upgraded. i was thinkin it was probobly the bugati but idk if the pagani zonda r is better or the ccx. so basicly which is better after fully upgraded ccx,bugati,or pagani zonda r once fully upgraded|||The Zonda is great, I heavily relied upon the Audi R8. The Veyron was fast, but was definitely hard to handle on certain tracks. Its really up to your personal preferences. I just wish Shift 2 was as good as Shift 1.
